And they dined out again on Sunday, reportedly enjoying a meal at Abe & Louie's restaurant where they indulged their sweet teeth with seven-layer chocolate cake and key lime pie.

With a romantic weekend behind them, the couple headed back to work – Katie to Long Island, New York, where she has been filming "The Romantics," and Tom to Salzburg, Austria, for a few days of shooting his upcoming summer 2010 action film, "Knight & Day."

Tom was snapped arriving on Thursday, waving to fans as he exited the private jet which brought him to Europe. "Knight & Day" co-star Cameron Diaz has been in town since Tuesday, according to the Associated Press.
